Folksvagen Sharan/Sharan repair>> The diesel engine>> shatunno - Piston group>> Removal and dismantling
Pistons and rods are beaten out from the block of cylinders in a direction upwards by the hammer handle, after removal of covers and loose leaves шатунных bearings.

Fig. 422. A kind of the top part of the engine. By arrows the big dredging for inlet valves which are differently located on pistons № 1 and 2, № 3 and 4 are shown

Put on each piston and a rod concerning it that number of the cylinder from which they have been removed. Is better to make it, having put cylinder number in colour on a piston bottom. Draw at the bottom of the piston an arrow specifying in a forward part of the engine. As the piston can be put on the contrary, i.e. is turned on 180 it is necessary to adhere fig. 422.

Fig. 423. By arrows cast ledges are shown. Languages of loose leaves of bearings settle down on the same party

At removal of the piston from a rod observe an exact direction of installation of a cover of a rod and right after removal put on a rod and a rod cover sideways cylinder number. Is better to do it кернером (for example, for the cylinder №1 — one blow кернером etc.). Rods and rod covers should be united so that both cast ledges have been located opposite each other (fig. 423). Both ledges after installation of rods always should be located from outside an intermediate shaft, and specify in that party of the engine where it is located приводной a belt.
On one party pistons have cut for atomizers of oil cooling to prevent collision of atomizers and pistons in the bottom dead point. Pistons should be established this party to atomizers.
After removal of covers of bearings of rods replace шатунные bolts.
Mark bearing loose leaves according to a rod and a rod cover. Also mark with a marker the top and bottom loose leaves of the bearing on their back party.
Remove covers шатунных bearings and loose leaves.
Beat out pistons and rods the handle of a plastic hammer from within the block of cylinders outside. In case of need scratch out a scraper an oil deposit on the top part of the cylinder, however be cautious not to damage thus a cylinder surface.

Fig. 424. Removal of a lock ring from an aperture for a piston finger. It is for this purpose used sharp оправка

Remove safety collars and squeeze out piston fingers. Dredging in an aperture for a piston finger facilitates tool use so you easily remove safety collars (fig. 424). Squeeze out a finger approaching оправкой.

Fig. 425. Removal or installation of piston rings

Fig. 426. The schematic image of removal or installation of piston rings

By turns remove through the piston bottom piston rings by means of a stripper (fig. 425). If you plan to establish again rings they should be marked in appropriate way. If you do not have stripper for piston rings you can insert under rings of a strip of metal the friend opposite to the friend. One of strips necessarily enclose under the lock of a ring to avoid occurrence of scratches (fig. 426).
